Abstract

The present invention relates to a nonaqueous composition for dispersing metal oxide particles. The nonaqueous composition comprises an ester dispersing media and a broad molecular weight distribution (MWD) polyester dispersing agent, each preferably synthesized from 100% biobased carbon. The ester dispersing media includes a liquid ester selected from the group consisting of: Formulas (I), (II), (III), (IV), and combinations thereof. The polyester dispersing agent has a polydispersity index (PDI) of greater than about 2.3. The present invention also relates to a nonaqueous dispersion comprising the nonaqueous composition above and metal oxide particles dispersed therein. The metal oxide particles may comprise zinc oxide, titanium oxide, or combinations thereof. Formulations using the compositions and dispersions as well as processes for preparing are also disclosed.
